Patent GB-594250-A (GB)
Title: Improvements relating to machines for grinding toothed gear wheels and analogous bodies
IPC: B23F23/10
Filed: 1945-05-03
Abstract: 594,250. Gear-cutting. WICKMAN, A. C. May 3, 1945, Nos. 11262 and 11882. [Class 83 (iii)] [Also in Group XXIII] In a machine for generating toothed gears, splined shafts &c. by means of a helically ribbed grinding wheel which is given axial motion relatively to the work during cutting in addition to its rotation in synchronism with the work, the axial motion is imparted by a screw and nut mechanism and the work rotation is dependent on the rotation of the screw mechanism so that compensatory rotation of the work is effected automatically. The grinding wheel f is carried by a spindle a which is driven by a splined sleeve d and belt drive b from an electric motor &c. c and is moved axially by a screw e secured thereto co-operating with an axially stationary driven nut g. The screw e has the same pitch as the helical rib on the wheel f. The nut is driven by gears u ... w with a 1 : 1 ratio from a shaft r rotated from the spindle a through a clutch t engageable with either of the gears p, q driven by a gear n on the sleeve d, the gears p, q being arranged to rotate .the nut at speeds respectively equal to and higher than the spindle speed for maintaining the latter axially stationary or traversing it in one direction. The shaft r may also be rotated from the intermediate shaft m through a one-way clutch o and gears k, s having a reduction ratio so that with clutch t in neutral the nut g is rotated at a lower speed than spindle a to traverse the spindle in the reverse direction. The nut g is connected to a spindle 14 carrying the work 15 through gearing 17, 19, 21 and 23, gears 21 being change gears, so that the work will be rotated at the correct meshing speed with the cutter f when the nut rotates at the same speed as the spindle a but will be rotated at the appropriate higher or lower speed when the nut is rotated relatively to spindle a. In operation, with the work and cutter rotating, fluid pressure is applied to a plunger 4 in a stationary casing 3 to move the plunger against a stop and displace the gears p, q into neutral position relatively to clutch t. The nut g is then driven at a low speed by gears k, s to traverse the spindle a in one direction and at the end of the traverse a dog 12 movable with the spindle displaces a ramp 11 to actuate a valve 9 and admit fluid to a plunger 5 in the casing 3. This plunger moves gear q against the clutch t and the nut g is therefor rotated at a higher speed to traverse the spindle a in the opposite direction. On release or failure of pressure to both plungers 4, 5, a spring y presses gear p against clutch t and the nut g then rotates with the spindle a. In a modification the nut may be attached to the spindle a and the screw rotated by the change speed gearing. A tool 31 may be used for trueing the wheel f, which is then driven by a motor 26 and gearing 29, h, n, (Group XXIII).

Title: Improvements in or relating to parking devices for motor vehicles
Inventor: BUTTERWORTH ARCHIBALD JAMES
IPC: B60S9/21
Filed: 1955-04-19
Abstract: 832,679. Vehicle jacks. SIDLER Ltd. April 13, 1956 [April 19, 1955], No. 11312/55. Classes 79(3) and 79(5) A vehicle parking mechanism comprises on each side of the vehicle a roller 18, Figs. 1 and 2, rotatably mounted on a support 14, a power-operated extensible structure 27 between the support and a fixed part 30 of the vehicle mounted so as to swing laterally toward and away from an adjacent road wheel 26, the support 14 being constrained to move laterally toward and away from the wheel, the roller being so shaped that a part 23 engages the road and a driving track 22 engages with the wheel or a part rotating therewith, whereby the wheel is lifted clear of the ground and the roller on engagement with the ground has its rotational axis inclined in a fore and aft direction. As further shown, in Figs. 1 and 2 the structure 27 is formed as a hydraulic cylinder pivoted at 28 to the differential housing of the rear axle casing 11 and a piston rod 31 is pivoted to the support strut 14 which is pivoted at 15 to brackets 13 on spring seats 10. Carried by the lower ends of the struts are the rollers 18 having conical sides 22 and conical bases 23 having depressions 24. In order to swing the rear end of the motor vehicle the cylinders 27 are pressurized to move them from Fig. 1 positions to Fig. 2 positions; in the latter positions the rear wheels 26 are off the ground and contact the tracks 22. In view of the disposition of the rollers engine drive of the wheels 26 in either direction will cause the rear end of the vehicle to be swung in either direction. In a modification, Fig. 6 (not shown), each support strut carries two rollers on parallel axes. The hydraulic pistons and cylinders may be fluid extended and spring retracted, Fig. 8 (not shown), or double acting, Figs. 13 to 16 (not shown). The rollers may be rotationally fixed relative to the strut by selection of the driver, Figs. 11 and 12 (not shown), the pistons and cylinders thus acting as built-in jacks. In another embodiment, Figs. 20 and 21 (not shown). the rollers are flatter than in Figs. 1 and 2, the roller sides engaging the wheel treads. In a further embodiment, Fig. 22, the ground engaging roller is fast with a roller 125 adapted to engage a disc 126 on the brake drum 127. The vehicle may carry a locking device to prevent the rollers being lowered while the vehicle is travelling at speed, the device permitting roller movement only when first or reverse gears are engaged. Alternatively the locking device may be released by a centrifugal, hydraulic or electric governor driven by the vehicle transmission. Specification 832,680 is referred to.

Title: Improvements in the manufacture of films from cellulose derivatives
IPC: C08L1/08
Filed: 1933-04-20
Abstract: <PICT:0403851/IV/1> Films suitable for photographic purposes are obtained from solutions of a cellulose derivative in a solvent mixture of which the individual constituents are non-solvents and include one or more constituents miscible with water in all proportions, and one or more constituents insoluble in water or not miscible in every proportion, and the latter constituent is present in a quantity at least twice that of the constituent which is miscible with water in all proportions.  The solution of the cellulose derivative is formed into a thin layer which is coagulated with an aqueous solution of an aliphatic alcohol miscible with water in all proportions.  In an example, a solution of nitrocellulose with a small proportion of camphor in a solvent mixture of ether and alcohol is introduced, in the form of a thin layer, into a bath of aqueous alcohol at a slightly raised temperature.  The film is stripped from the forming surface and washed.  It may then be coated with gelatine.  In another example, a solution of cellulose acetate with tripropylphosphate as plasticiser in a mixture of methylene chloride, methyl alcohol, and ethyl alcohol is formed into a film with the aid of a coagulating liquid consisting of aqueous methyl alcohol.  In another example nitroethyl cellulose dissolved in a mixture of benzene and ethyl alcohol is formed into a film with the aid of n-propyl alcohol and water.  The coagulating liquid may enter the bath at the place where the film is stripped from the drum or other forming surface, and flow in countercurrent to the film.  The use of a drum or like surface may be dispensed with.  As shown in the drawing, a cellulose derivative solution issues from a slot, into a flowing precipitating liquid 3 where it coagulates in the form of a sheet 2 which is carried with the liquid through the chamber 8 to the chamber 4.  The film is then taken over rollers and passed through a washing tank 7 on its way to a drying chamber.  The liquid from chamber 4 is pumped back to the supply tank 6.  Specification 347,423 is referred to.
